Field validations currently run very often, such as within form state on
type. This can lead to serious performance implications within the admin
panel if those validation functions are async, especially if they
perform expensive database queries. One glaring example of this is how
all relationship and upload fields perform a database lookup in order to
evaluate that the given value(s) satisfy the defined filter options. If
the field is polymorphic, this can happen multiple times over, one for
each collection. Similarly, custom validation functions might also
perform expensive tasks, something that Payload has no control over.
The fix here is two-fold. First, we now provide a new `event` arg to all
`validate` functions that allow you to opt-in to performing expensive
operations _only when documents are submitted_, and fallback to
significantly more performant validations as form state is generated.
This new pattern will be the new default for relationship and upload
fields, however, any custom validation functions will need to be
implemented in this way in order to take advantage of it. Here's what
that might look like:
```
[
// ...
{
name: 'text'
type: 'text',
validate: async (value, { event }) => {
if (event === 'onChange') {
// Do something highly performant here
return true
}
// Do something more expensive here
return true
}
}
]
```
The second part of this is to only run validations _after the form as
been submitted_, and then every change event thereafter. This work is
being done in #10580.

Important
🎉 We've released 3.0! Star this repo or keep an eye on it to follow along.
Payload is the first-ever Next.js native CMS that can install directly in your existing /app folder. It's the start of a new era for headless CMS.
Benefits over a regular CMS
- Deploy anywhere, including serverless on Vercel for free
- Combine your front+backend in the same
/appfolder if you want - Don't sign up for yet another SaaS - Payload is open source
- Query your database in React Server Components
- Both admin and backend are 100% extensible
- No vendor lock-in
- Never touch ancient WP code again
- Build faster, never hit a roadblock
Quickstart
Before beginning to work with Payload, make sure you have all of the required software.
pnpx create-payload-app@latest
If you're new to Payload, you should start with the website template (pnpx create-payload-app@latest -t website). It shows how to do everything - including custom Rich Text blocks, on-demand revalidation, live preview, and more. It comes with a frontend built with Tailwind all in one /app folder.
One-click templates
Jumpstart your next project by starting with a pre-made template. These are production-ready, end-to-end solutions designed to get you to market as fast as possible.
🌐 Website
Build any kind of website, blog, or portfolio from small to enterprise. Comes with a fully functional front-end built with RSCs and Tailwind.
We're constantly adding more templates to our Templates Directory. If you maintain your own template, consider adding the payload-template topic to your GitHub repository for others to find.
